Abstract
A strap retractor assembly of a seat belt arrangement including a retaining strap to be fitted to an occupant of a seat in a vehicle, comprising a reel shaft having the retaining strap anchored thereto; a drive motor for driving the reel shaft for rotation in direction to have the retaining strap unwound from and re-wound on the reel shaft; pulse generators to produce first pulses in response to rotation of the reel shaft in one direction and second pulses in response to rotation of the reel shaft in the other direction; a pulse counter to count the first pulses forwardly and the second pulses backwardly for producing an information signal representative of the number of the pulses counted; a reference signal generator to produce a reference signal variable with a preselected parameter and representative of a number of pulses corresponding to a desired degree of slackness of the strap; comparators to produce a signal when the number of the pulses represented by the information signal is in a predetermined relationship to the number of pulses represented by the reference signal; and a signal processing network to process the signals and pulses delivered from the pulse generators and comparators and to produce, on the basis of the signal from the comparators, a signal to actuate the motor into operation driving the reel shaft in either direction.
